IMPORTANT SAFETY INSTRUCTIONS

INSTRUCTIONS PERTAINING TO A RISK OF FIRE, ELECTRIC SHOCK, OR INJURY TO PERSONS
WARNING – When using tools, basic precautions should always be followed, including the following:

1. Wear ANSI-approved safety goggles during setup and use of the Battery Tester.

2. Test in a well-ventilated area. Explosive gases may be produced during testing. Do not smoke, cause sparks, or strike matches near the battery when testing.

3. Refer to the user manual of the Battery being tested for testing instructions and precautions prior to using the Battery Tester.

4. Do not connect in reverse polarity.

5. Do not expose this product to rain or wet conditions.

6. Maintain this product. Check for breakage of parts and any other condition that may affect this product’s operation. If damaged, have the unit repaired before use.

7. Use this product in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of this product for operations different from those intended could result in a hazardous situation.

8. This product is not a toy. Keep it out of reach of children.

9. Maintain labels and nameplates on the unit. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.

10. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to the heart pacemakers could cause pacemaker interference or pacemaker failure. Caution is necessary when near coil, spark plug cables, or distributor of running engine. The engine should be off during distributor adjustment.

11. Undercharged lead-acid batteries will freeze during cold weather.
    Do not test or charge a frozen battery.
    

12. When connecting the Battery Cables to the battery, avoid creating sparks; especially when the battery is being charged. Explosive gases are created during charging. Sparking could also damage the vehicle’s electrical system.

13.  Do not touch the cooling vents on the Battery Tester during or immediately after testing the battery. They become very hot.

14. When placing the Battery Tester in the vehicle’s engine compartment, take special care that the metal housing of the Tester does not come in contact with either terminal of the battery or other electrical connections.

15. Be certain of the test battery polarity before connecting the test Cable Clamps. The red Cable Clamp goes to the positive terminal of the battery. The black Cable Clamp goes to the negative terminal of the battery. Reversing Battery Tester Cable Clamps on the battery will damage the tester

16. Do not drop the Battery Tester as it may affect proper operation.

17. Do not smoke or have open flames near the battery.

18. Do not connect the Battery Tester to the battery while the engine is running. Turn the engine off before connecting.

19. The warnings and precautions discussed in this manual cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors that cannot be built into this product but must be supplied by the operator.

Operating Instructions

**** Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

Testing the Battery

1.  To help ensure a good connection, wipe the battery terminals with a cloth to remove any dirt and grease.
2. Connect the red (positive) Cable Clamp to the positive terminal (+) on the 6 or 12V lead-acid battery. See figure A.
3. Connect the black (negative) Cable Clamp to the negative terminal ( –) on the battery. See figure A. Turn clamps slightly to ensure a good connection.
4. With the clamps connected, the tester’s gauge will show the battery’s current charge. See figure B. If it is less than 12V, disconnect the battery and recharge before testing. If the recharging will not bring the reading above 12V, the battery is defective. If it shows no reading, verify that the tester is connected properly. If the tester is connected
5. Press (and hold) the Toggle Switch for at least 5 seconds to simulate an actual load on the battery. See figure A.
6. View the Meter Display and read the battery condition. Refer to the “Battery Condition Analysis” chart on page 6.
7. Release the Toggle Switch and remove the Cable Clamps from the battery.

Testing the Charging System

WARNING

AVOID CARBON MONOXIDE POISONING. This gas comes from the vehicle’s exhaust and is colorless and odorless. It can cause SERIOUS INJURY or DEATH if inhaled.

1. Connect the Cable Clamps to the battery as previously described.
2. Outside, or in a well-ventilated area, start the vehicle engine and run at fast idle speed.
3. View the Meter Display and read the charging system condition (far right on the gauge). Refer to the “Battery Condition Analysis” section to the right.
4. Turn the vehicle’s engine off, then remove Cable Clamps.

Testing the Starter

NOTE: The engine should be at normal operating temperature and the battery should be fully charged before doing this test.

1. Connect the Cable Clamps to the battery as previously described.
2. Disable the ignition so the engine will not start. (Refer to your vehicle’s manual.)
3. Have an assistant crank the engine. Note the voltage reading during cranking.
4. View the Meter Display and read the voltage. A reading of 9 Volts or less indicates excessive current draw. This may be due to a poor connection, a failing starter, or a battery of insufficient size for the motor.
5. When finished, disconnect the Cable Clamps, restore ignition, and store the tool in a clear, dry location away from children.

Battery Condition Analysis

Load Test / 15 Seconds (Display Reading)

|

Battery Condition

---|---
OK (Green Area)| The battery capacity is good. May or may not be fully charged. Check the charge state by testing the Specific Gravity (SG) with a Hydrometer (not included). If SG is less than a full charge, check for possible charging system trouble. Recharge to full level.
Weak (Yellow Area)| If the Display Meter needle is steady, the battery capacity is not good. The battery may be defective or partly discharged. Check SG. If over 1.225, the battery is defective. If below 1.225, recharge the battery and retest. If there is a difference in SG between cells over 2 points (0.025), a particular cell may be damaged. If charging does not bring SG to full charge level, then the battery is either sulfated or has lost its active material.
Bad (Red Area)| If the Display Meter needle is falling, the battery is defective or has a bad cell. For a quick check, release the load Toggle Switch and note the Display Meter reaction. If voltage recovers to its full potential after only a few seconds, the battery is probably defective. If the voltage recovers slowly, the battery may only be run down. Check SG, recharge, and retest.
Charging System (Alt. & Reg Test)| If the Display Meter needle reads OK, the charging system is functional. If it falls on the low red or high red areas, the charging system may be malfunction.
